Domain: Setting this option to Domain respects the upstream domain of definition
when applying the node’s effect. This can have adverse clipping effects in situations
where the node employs a large filter.
None: Setting this option to None does not perform any source image clipping at all.
This means that any data required to process the node’s effect that would normally be
outside the upstream DoD is treated as black/transparent.

The Settings tab in the Inspector is also duplicated in other Blur nodes. These common controls
are described in detail at the end of this chapter in “The Common Controls” section.
Directional Blur [DRBL]
The DirectionalBlur node
Directional Blur Node Introduction
This node is used to create Directional and Radial blurs. It is useful for creating simulated motion
blur and light ray-type effects. Directional Blur affects all channels (RGBA).
Inputs
The two inputs on the Directional Blur node are used to connect a 2D image and an effect
mask which can be used to limit the blurred area.
Input: The orange input is used for the primary 2D image that has the directional blur
applied.
Effect Mask: The blue input is for a mask shape created by polylines, basic primitive
shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input
limits the directional blur to only those pixels within the mask. An effect mask is
applied to the tool after it is processed.
Basic Node Setup
The Directional Blur node receives a 2D image like the MediaIn1 shown below. The output
continues the node tree by connecting to another 2D image-processing node or a Merge node.
